    the calculator s usage! after you have inputed 2 operators,choose + - * / function! But the only situation I did t deal with is that when you choos + fuction ,and the operaters signs is like this -A+B,just turn it to B-A!

  • CRC16算法的Java实现

    CRC16算法的Java实现,使用方法如下: CRC16 crc16 = new CRC16() byte[] b = new byte[] { // (byte) 0xF0,(byte)0xF0,(byte)0xF0,(byte)0x72 (byte) 0x2C, (byte) 0x00, (byte) 0xFF, (byte) 0xFE, (byte) 0xFE, (byte) 0x04, (byte) 0x00, (byte) 0x00, (byte) 0x00, (byte) 0x00 } for (int k = 0 k < b.length k++) { crc16.update(b[k]) } System.out.println(Integer.toHexString(crc16.getValue())) System.out.println(Integer.toHexString(b.length))

  • GPS系统接收数据坐标转换 GPS接收的数据往往是三维坐标

    GPS系统接收数据坐标转换 GPS接收的数据往往是三维坐标,而在科学研究中我们通常用二维坐标。因此必须 进行坐标转换,下面我们介绍一种坐标转换,即把WGS84坐标转换为高斯—克吕 格坐标系。数字地图投影的方法很多,而我国采用了高斯—克吕格投影,它是一 种横轴椭园柱面等角投影,用一个椭球柱面与地球椭球在某一子午圈L0上相切, 这条子午线通常称做投影轴子午线。也就是高斯-克吕格投影直角坐标系的x 轴, 地球的赤道与椭圆柱面相交, 成一直线,这条直线与轴子午线正交,就是平面直角坐 标系的y轴,把椭球柱面展开,就得到以(x,y)为坐标的平面直角坐标系。为减少 投影变形,按经度把椭球分为许多带,各带分别投影,经常采用的是3度和6度带。 为使y值不为负值,通常在y轴上加上500km。 已知WGS84坐标(B,L),B为GPS定位输出成果的纬度,L为GPS定位输出成果的经度。 由WGS84到高斯-克吕格坐标(x,y)的转换成高斯投影正算,详见本软件

  • 创建两个生产者进程和两个消费者进程

    创建两个生产者进程和两个消费者进程,生产者进程a需要生成10000个整数,每次都将自己的进程号(用getpid()函数获得)和生成的整数放入共享内存中(共享内存大小为64Byte)。生产者b每次从26个英文字母中选一个,并将自己的进程号和选中的字母放入共享内存中,直到26个字母全部都选中。消费者进程c负责从共享内存中读取数据生产者进程a的数据并且将这些数据写入文件a.out。消费者进程d从共享内存读取进程b的数据后写入b.out中。

    This article describes how to consume Web services in Java 1.5.0 using the new JAX-WS 2.0 API (JSR 228). Developers around the world, including me, have always complained about the hard ways to work in Java to consume even a Web service as simple as adding two numbers. However, with JAX-WS 2.0 API now available in core Java in JDK 1.5.0, life is simple like never before.

    In computer vision, sets of data acquired by sampling the same scene or object at different times, or from different perspectives, will be in different coordinate systems. Image registration is the process of transforming the different sets of data into one coordinate system. Registration is necessary in order to be able to compare or integrate the data obtained from different measurements. Image registration is the process of transforming the different sets of data into one coordinate system. To be precise it involves finding transformations that relate spatial information conveyed in one image to that in another or in physical space. Image registration is performed on a series of at least two images, where one of these images is the reference image to which all the others will be registered. The other images are referred to as target images.
